ELECTROSTATIC CONDENSER.

Application filed January 19, 1925. Serial No. 3,399.

To all whom t may concer/n.:

Be it known that I, PETER G. JAoonsoN, a citizen of the United States, residing at Chicago, in the county of Cook and the State of Illinois, have invented a certain new and useful Improvement in Electrostatic Gondensers, of which the following is a full, clear, concise, and exact description.

My invention relates to electrostatic condensers and has for its object the provision of improved means for assembling plates thereof. p

My invention is of particular service in connection with those condensers whose sides are in the form of stators and rotors, the device of my invention being of particular vservice in assembling the plates of rotors, though the invention is not to be thus restricted.

In carrying out my invention I employ a tube formed in two longitudinal sections,

each section being formed with a row of transverse fingers along each longitudinal side thereof that intermesh with the rows of transverse fingers along the opposite longitudinal sides of the other section, respectively, the condenser plates being distributed along the tube and interposed between meshing fingers at both sides of the tube, these fingers having clamping engagement with said plates. I

The invention will be more fully explained in connection with the accompanying drawing in which Fig. 1 is an elevation partially in section, showing the preferred form of condenser; Fig. 2 is a plan view of the condenser with portions broken away; Fig. 3 is a sectional view on line 3--3 of Fig. 1 on a larger scale; Fig. 4 is a. sectional view on line 4 4 of Fig. l; Fig. 5 is a view showing the plate holding tube minus the plates; Fig. 6 is a sectional view on line 6 6 of Fig. 5; Fig. 7 shows the tubesections of Figs. 5 and 6, developed, the planes of the plates being indicated by dotted dash lines; Fig. 8 is a detail view of the portion of a condenser plate where assembled with the tube; Fig. 9 is a view similar to Fig. 6 but showing the condenser plate portion of Fig. 8, in assembly therewith; and Fig. 10 is a sectional view on line 10-10 of Fig. 9.

The stator of the condenser is composed of a plurality of metallic plates 1, preferably triangular, which are formed with notches 2 that receive the assembling rods 3. Metallic washers 4 are interposed between adjacent plates to maintain them in suitably spaced apart relation, these washers surrounding the assembling rods 3. End washers 5 also surround the rods 3, to maintain the group..` of stator plates a suitable distance from the condenser 'fraine'sides 6 and 7. The rods are provided with heads 8 which are received within insulating thimbles 9 that are received in the frame sides 7, the thimbles being disposed upon the outer faces of this frame side. Insulating washers 10 are disposed upon the one face of the frame side 7 and are interposed between the adjacent washers 5 and this frame side. The rods at their other ends, are provided with nuts 11 which are screwed thereon, the frame sides 6 being sandwiched between the insulating washers 12. Y

The rotor of the condenser includes a group of metallic plates 13, here shown as being semi-circular. These plates are alternated with the plates 1 of the stator and are carried upon the oscillatable shaft 14. This shaft is carried at one end within the bearing 15 provided in the frame side 7 and at its other end on the bearing 16 carried in the frame side 6. The plates 13 are directly carried upon a tube formed in two parts 17 and 18, the method of assembly of these plates with this tube being hereinafter set forth. rlhe tube has end walls 19 and 2O which surround the shaft 14, the end wall 2O being screwed upon the shaft and the end wall 19 being pressed toward the end wall 2O by the clamping nut 21 also screwed upon the shaft. The bearing 16 desirably has a conical seat upon its inner end, this conical seat receiving the conically shaped reduced section of the shaft 14, this shaft having a further reduction 22 which is continued through the bearing 16. This bearing is screwed in the frame side 6 and is clamped in assembly therewith by the clamping nut 23. The outer end of the bearing 16 is formed with screw driver slots 24 whereby this bearing may be turned in one direction. or the other to secure the proper relationship of the plates 13 with respect to the plates 1. A spring 25 is interposed between the sleeve end wall 2O and the bearing 15 and maintains the shaft 14 in proper engagement with the bearing 16 in the various adjustments ot the group of plates 13 that may be effected by turning the bearing 16 1n either direction.

The sections 17 and 18 ol the tube which carries the plates 13 are desirably stamped out of liat sheets of metal to have the shape in Fig. 7 before being curled in the direction ol' the tube. Each longitudinal tube section 17, 18 is lormed with a row of transverse lingers 26 along each longitudinal side thereof. Each tube section together with its transverse lingers is curled'to form 'a segment ol thetube, theadjacent rows ol fingers of the assembled tube sections intermeshing to constitute the complete tube. Gaps 27 are left-between adjacent intermeshing lingers, the 4plates 'having tongue continuations 28 that are passed through these gaps into the tube. In' the vprocess of the assemblyT of the tube and the plates 13 these plates are held in suitablespaced apart relation 'and in such position with respect to the gaps 27 as to be entered within the same. The curling of the lingerslnay be eliected or completed while the plates 13 are thus held, the interaction olil the lingers being such as to lirinly clamp the plates in the gaps 27 receiving' the same. To preyent the plates 13 from turning with respect to each other and with respect to the tube, the tongues 28 of the plates are suitably formed with shoulders 29 at ends of the gaps between the lingers. The plates are desirably provided also, with lugs 30 between lthe tongues 28 thereof, these lugs entering recesses 31 that are formed along the tube section 18 between the rows oi transverse lingers thereon. The tongues 28 are desirably snugly engaged with one side of the shaft 111 to insure a lixed relation by this shalt, these plates, and the tube 17, 1S which directly carry the plates. The shalt may be l'orwardly continued through a panel board and there may be provided with an adjusting knob or handle to regulate the capacity of the condenser.

Changes may be made without departing 'from my invention.

Having thus 'described my invention I claim':
